FIG. 6 is a flow diagram illustrating an embodiment of a process for providing a spreadsheet cell data flow view. In some embodiments, the process of FIG. 6 comprises a process for providing the spreadsheet cell data flow view of FIG. 4. In the example shown, in 600, a spreadsheet is received. In some embodiments, the spreadsheet comprises a spreadsheet of a set of spreadsheets. In 602, an indication of a spreadsheet cell of interest is received. In some embodiments, the indication of a spreadsheet cell of interest is received from a spreadsheet view (e.g., from a traditional view of the spreadsheet). In 604, a first set of spreadsheet cells that the spreadsheet cell of interest depends on is determined. In some embodiments, the first set of spreadsheet cells comprises all spreadsheet cells that the spreadsheet cell of interest depends on. In some embodiments, the first set of spreadsheet cells is displayed in a cell level data flow view on the left side of the spreadsheet cell of interest (e.g., as data dependencies flow left to right). In 606, a second set of spreadsheet cells that depend on the spreadsheet cell of interest is determined. In some embodiments, the second set of spreadsheet cells comprises all cells that depend on the spreadsheet cell of interest. In some embodiments, a cell cannot be part of both the set of cells determined in 604 and the set of cells determined in 606.

In 608, a spreadsheet cell data flow view for the spreadsheet cell of interest is provided based at least in part on the first set of spreadsheet cells and the second set of spreadsheet cells. In some embodiments, the spreadsheet cell data flow view is based at least in part on security information. In some embodiments, a determination of whether a cell is part of the first set of spreadsheet cells or whether a cell is part of the second set of spreadsheet cells is based at least in part on security information (e.g., if the user requesting the spreadsheet cell data flow view is not allowed to access a cell, the cell is never included as part of the first set of spreadsheet cells or the second set of spreadsheet cells). In some embodiments, a label (e.g., a row label or a column label) associated with a spreadsheet cell of the spreadsheet is determined. In some embodiments, the spreadsheet cell data flow view is based at least in part on the label (e.g., the label is shown associated with its associated cell of the spreadsheet). In 610, it is determined whether an indication of a new spreadsheet cell of interest is received. In the event it is determined that an indication of a new spreadsheet cell of interest is received, control passes to 604. In the event it is determined that an indication of a new spreadsheet cell of interest is not received, control passes to 612. In 612, it is determined whether an indication to view a spreadsheet view is received. In some embodiments, in the event it is determined that an indication to view a spreadsheet view is not received, the process ends. In the event it is determined that an indication to view a spreadsheet view is received, control passes to 614. In 614, a spreadsheet view for the spreadsheet is provided. In some embodiments, in the event an indication to edit a spreadsheet cell is received, an interface to edit the spreadsheet cell is provided. In some embodiments, a spreadsheet cell data flow view comprises multiple levels of dependencies (e.g., not just cells that depend on the spreadsheet cell of interest, but cells that depend on those cells). In some embodiments, a spreadsheet cell data flow view comprises all spreadsheet cells, regardless of the number of levels of dependencies. In some embodiments, a spreadsheet cell data flow view comprises a user-defined number of levels of dependencies (e.g., a system user indicates the number of levels of dependencies desired to be shown). In some embodiments, a spreadsheet cell data flow view comprises only spreadsheet cells of interest at each dependency level.

FIG. 7 is a flow diagram illustrating an embodiment of a process for determining spreadsheets of a set of spreadsheets that a spreadsheet of interest depends on. In some embodiments, the process of FIG. 7 implements 504 of FIG. 5. In the example shown, in 700, the next cell of the spreadsheet of interest is selected. In some embodiments, the next cell comprises the first cell. In 702, it is determined whether the selected cell depends on cells of any other spreadsheets (e.g., any other spreadsheets of the set of spreadsheets). In the event it is determined that the selected cell does not depend on cells of any other spreadsheets, control passes to 706. In the event it is determined that the selected cell depends on cells of other spreadsheets, control passes to 704. In 704, spreadsheets comprising cells the selected cell depends on are added to the list of spreadsheets that the spreadsheet of interest depends on. In 706, it is determined whether there are more cells in the spreadsheet of interest. In the event it is determined that there are more cells in the spreadsheet of interest, control passes to 700. In the event it is determined that there are not more cells in the spreadsheet of interest, the process ends.

In some embodiments, each spreadsheet of the set of spreadsheets comprises a list of other spreadsheets the spreadsheet depends on. The list is empty when the spreadsheet is created. When a spreadsheet cell is modified, it is determined whether the modification changes the list of other spreadsheets the spreadsheet depends on (e.g., adds a spreadsheet to the list or removes a spreadsheet from the list). Determining spreadsheets of the set of spreadsheets that a spreadsheet of interest depends on then comprises reading the list associated with the spreadsheet of interest.

In some embodiments, a spreadsheet of interest depending on an other spreadsheet indicates that a cell of the spreadsheet of interest depends on a cell of the other spreadsheet.

FIG. 8 is a flow diagram illustrating an embodiment of a process for determining spreadsheets of a set of spreadsheets that depend on a spreadsheet of interest. In some embodiments, the process of FIG. 8 implements 506 of FIG. 5. In the example shown, in 800, the next spreadsheet of the set of spreadsheets is selected. In some embodiments, the next spreadsheet comprises the first spreadsheet. In 802, dependencies of the selected spreadsheet are determined. In some embodiments, dependencies of the selected spreadsheet are determined by determining dependencies of each cell of the selected spreadsheet. In some embodiments, dependencies of the selected spreadsheet are determined by accessing a dependency list associated with the spreadsheet (e.g., the list is updated each time the dependencies of the cells of the spreadsheet are updated). In 804, it is determined whether the selected spreadsheet depends on the spreadsheet of interest (e.g., whether the spreadsheet of interest is included in the dependencies determined in 802). In the event it is determined that the selected spreadsheet does not depend on the spreadsheet of interest, control passes to 808. In the event it is determined that the selected spreadsheet depends on the spreadsheet of interest, control passes to 806. In 806, the selected spreadsheet is added to the list of spreadsheets that depend on the spreadsheet of interest. In 808, it is determined whether there are more spreadsheets (e.g., in the set of spreadsheets). In the event it is determined that there are more spreadsheets, control passes to 800. In the event it is determined that there are not more spreadsheets, the process ends.

FIG. 9 is a flow diagram illustrating an embodiment of a process for determining a first set of spreadsheet cells that a spreadsheet cell of interest depends on. In some embodiments, the process of FIG. 9 implements 604 of FIG. 6. In the example shown, in 900, spreadsheet cell dependencies are determined from the spreadsheet cell formula. In some embodiments, the spreadsheet cell formula comprises the definition of the calculation stored by the spreadsheet cell, including any dependencies of the spreadsheet cell. In some embodiments, a spreadsheet cell of interest depending on an other spreadsheet cell indicates that the cell formula of the spreadsheet cell of interest comprises a dependency on the other spreadsheet cell (e.g., a formula in a first cell includes a reference to a second cell, a third cell is referred to in a formula in a fourth cell, etc.).

FIG. 10 is a flow diagram illustrating an embodiment of a process for determining a second set of spreadsheet cells that depend on a spreadsheet cell of interest. In some embodiments, the process of FIG. 10 implements 606 of FIG. 6. In the example shown, in 1000, the next spreadsheet cell of the spreadsheet (e.g., the spreadsheet comprising the spreadsheet cell of interest) is selected. In some embodiments, the next spreadsheet cell comprises the first spreadsheet cell. In 1002, spreadsheet cell dependencies of the selected spreadsheet cell are determined. In some embodiments, spreadsheet cell dependencies are determined from the spreadsheet cell formula. In 1004, it is determined whether the selected spreadsheet cell depends on the spreadsheet cell of interest (e.g., whether the spreadsheet cell of interest is included in the dependencies determined in 1002). In the event it is determined that the selected spreadsheet cell does not depend on the spreadsheet cell of interest, control passes to 1008. In the event it is determined that the selected spreadsheet cell depends on the spreadsheet cell of interest, control passes to 1006. In 1006, the selected spreadsheet cell is added to the list of spreadsheet cells that depend on the spreadsheet cell of interest. In 1008, it is determined whether there are more cells. In the event it is determined that there are more cells, control passes to 1000. In the event it is determined that there are not more cells, the process ends.

FIG. 11 is a flow diagram illustrating an embodiment of a process for providing a spreadsheet view for a spreadsheet. In some embodiments, the process of FIG. 11 implements 614 of FIG. 6 or 514 of FIG. 5. In the example shown, in 1100, a spreadsheet view of the spreadsheet cells is provided (e.g., displaying spreadsheet cells in a traditional grid layout). In 1102, it is determined whether an indication to view a spreadsheet data flow view is received. In the event it is determined that an indication to view a spreadsheet data flow view is not received, control passes to 1106. In the event it is determined that an indication to view a spreadsheet data flow view is received, control passes to 1104. In 1104, a spreadsheet data flow view is provided (e.g., according to the process of FIG. 5), and the process ends. In 1106, it is determined whether an indication to view a spreadsheet cell data flow view is received. In the event it is determined that an indication to view a spreadsheet cell data flow view is not received, the process ends. In the event it is determined that an indication to view a spreadsheet cell data flow view is received, control passes to 1108. In 1108, a spreadsheet cell data flow view is provided.
